FOUNTAIN-PEN.

SPECIFICATION formingpart of Letters Patent No. 726,495, dated April 28, 1903.

Application filed November 22,1902 Serial No. 132.494. (No model.)

To all whmn it ntay concern.-

Be it known that 1, JOHN BARNES, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in FountaimPens, of which the following is a specification.

The object of this invention is to construct a fountain-pen employing an elastic ink-reservoir and a lever for compressing aportion of the reservoir in order that a vacuum may be created, and in allowing the wall of the reservoir to assume its normal position ink will be drawn in through the open end of the res ervoir.

In the accompanying drawings, Figure 1 is lengthwise section of the casing of the pen with the parts in their normal position. Fig. 2 is a similar section in which the ink-reservoir is compressed. Fig. 3 is a transverse section on dotted line a, Fig. 2. Fig. 4 is an isometrical representation of the plate, end plug, and their connections. Fig. 5 is an isometrical representation ofthe lever.

The casing 1 of the pen, the elastic inkreservoir 2, and the penholder 3 are of an old construction. A slot 4 is formed in the casing 1. Between the outer wall of the elastic ink-reservoir and the inner wall of the casing is located a plate (shown at Fig. 4) which comprises the base portion 5 and inturned edges 6, forminga groove. To one end of the base portion is connected achain or link 7,and the other end of the chain or link is connected to a plug 8, fitted to enter the open end of the casing. Within the slot 4 is located a lever (shown at Fig. 5) comprising the handle portion 9 and shorter end 10, formed with the sideprojectionsll. Byturningtheshorterend so that the projections lie in the lengthwise direction of the slot 4 it may be located within the slot, and, a pin 12 passing through the opening 13 and openings in the casing, a pivotal'connection is formed between the lever and casing. The plate is pushed in between the outer wall of the elastic ink-reservoir and the inner wall of the casing and engages the projections 11 of the lever by the projections passing under the inturned side walls 6, thereby forming a connection between lever and plate. The plate can be withdrawn by taking out the plug 8 and pulling on it. By this arrangement the plate extends nearly the length of the flexible elastic ink-reservoir in order that the walls of the reservoir may be compressed to create avacuum, and upon moving the lever into its normal position the expansive force of the material comprising the ink-reservoir will cause its walls to assume their normal position, and in doing soink will be drawn in through the open end of the pen. The connection between the lever and plate holds these parts in their relative positions. \Vhen the parts are in their normal positions, the longer arm of the lever will lie in the lengthwise direction of the casing and nearly concealed within the groove 4. By the employment of a lever having a short arm engaging the plate and the longer arm to be moved by the user of the pen a greater pressure is brought to bear upon the elastic ink-reservoir, and the employment of an ink-reservoir having extra thick walls, which will insure an expansive force sufficient to draw in the ink and fill the reservoir.

I do not limit my invention to the use of a plate with the groove, as any other compressing device interposed between the casing and elastic ink-reservoir upon which the lever exerts its influence can be employed.

I claim as my invention 1. A fountain-pen comprising an outer casing, an elastic ink-reservoirlocated within the casing, a compressing device located between the reservoir and casing and a lever, having an engagement or connection with the de'- vice and easing, by means of which the elastic ink-reservoir is compressed.

2. A fountain-pen comprising an outer casing, an elastic ink-reservoir located within the casing, a plate located between the reservoir and easing, a lever having one end in engagement with the plate and its other end extending through an opening in the casing and having an engagement with the casing intermediate its'ends.

3. A fountain-pen comprising an outer casing, an elastic ink-reservoir located within the casing, a lever having a pivotal connection with the casing, and a plate located between Disclaimer in Letters Patent No. 726,495.
